Product Description

Standard service routine: for positive and negative pressure masks: includes complete disassembly of demand valve, checking and removal of corrosion to metallic components, Ultra-sound cleaning of all components, checking all parts for integrity and proper function, rebuilding and lubricating, replacing hose connection O-rings and inner mask discs and testing the hose to 20 bar.

After adjustment, your mask is tested according to EN250 and the Manufacturer’s maintenance manual. Dynamic performance tests are recorded and noted against the job number, which record we keep for five years, as is required under CoSHH regulations (breathing apparatus) and BS EN 529:2005 (Respiratory protective devices. Recommendations for selection, use, care and maintenance).

Should other parts be required, we will advise you, prior to fitting them. When other parts, such as demand and exhation diaphragms are required, they are charged extra at our published prices.

Usually, other O-rings and rubber parts will need replacement after about six years of service, dependent of the amount of use and the degree of after use care and cleaning you have given the mask.
